Answers may vary but might include increased energy consumption, burning of fossil fuels, cutting down of forests, overfishing in our oceans, and increased water consumption.
Recycling, reusing products, using alternative energy sources such as solar, driving electric cars, policies to protect the environment, etc.
Cutting down of tropical rainforests, climate change, increased human population, the destruction of habitats to build new homes, illegal hunting or poaching, etc.
Human activities are causing increased greenhouse gases in our atmosphere that traps heat and increases temperatures. The burning of fossil fuels for transportation and factories is a major source of greenhouse gas emissions.
Glaciers are shrinking, sea levels are rising, warmer winters, changes in precipitation patterns, more droughts and heat waves leading to increased fires, stronger hurricanes, etc.
Air pollution such as smog in cities, contaminated drinking water, plastics in our oceans, the accumulation of trash in cities and landfills, etc.
The Industrial Revolution brought about many advancements in science, technology, and medicine along with improved nutrition that caused people to live longer.
There is an increased demand on our natural resources including trees for making products such as paper and furniture, water for drinking, and minerals to make products such as phones and fertilizers.
The creation of new laws and wildlife preserves have helped to protect animals like the bison come back from being close to extinction due to overhunting. New regulations as well as innovative ways of reseeding and replanting corals has helped Belize’s coral reefs come back from oil spills. Conservational biologists established a wildlife preserve to save the giant panda from becoming extinct in China.
Using alternative energies such as solar energy, using biodiesel that is made from plants rather than oil, carpooling to school or work, turning off cars while waiting to pick someone up, and using public transportation.
Bioplastics are biodegradable and break down in the environment much faster, reducing the amount of plastics in our oceans and landfills over time.
The increased human population has increased our need for freshwater, and we use over four times as much freshwater as we did only fifty years ago. Since only 1% of the water on our planet is fresh water, this is a limited natural resource. Some things we can do to conserve freshwater are taking shorter showers, turning off the water when you are washing your hands or brushing your teeth. Scientists and engineers have developed ways to turn saltwater into freshwater, but it is expensive and requires a lot of energy. More innovations in science and engineering may be able to help solve this problem in the future.
The number of humans living in a particular area.
Materials or substances such as minerals, forests, water, and fertile land that occur in nature and are necessary or useful to humans.
A natural resource that is replenished by natural processes at a rate comparable to its rate of consumption.
A resource that will not return, or renew, or will only return after a long period of time.
A group of animals, plants, or other living things that all share common characteristics.
The end of existence of a species of plant or animal.
Protected natural areas that are important in maintaining biodiversity or conducting scientific study.
Prevention of wasteful use or protection of natural resources.
The application of scientific knowledge to create tools and machines that may be used to solve real-world problems.
What are two ways that the landfill in the video tries to reduce its impact on the environment?
What are 3 properties of plastic that make it a useful material? What happens when it gets into the environment?
What are two ways that people can reduce our impact on the environment?
"My students loved the videos. I started the video subscription in May and used them as a review before the state test, which I know contributed to 100% of my class passing the state test."
